University students across South Korea have issued a joint declaration demanding institutional reform after a ballot shortage forced the temporary suspension of voting at 91 polling stations during the June 3 local elections, leaving some citizens unable to cast their ballots. Student councils from 18 universities — including Seoul National University, Yonsei University, and Korea University — released the statement on June 10, framing the shortage not as a bureaucratic mishap but as a violation of the constitutionally guaranteed right to vote. The declaration, the first joint student statement on a major political issue since a collective response to a December 2024 martial law crisis, has prompted President Lee Jae-myung to order a formal investigation, with prosecutors and police conducting searches of the National Election Commission and several regional offices.
